Numbers 5:20

¹⁸And the priest shall cause the woman to stand before the Lord, and shall uncover the head of the woman, and shall put into her hands the sacrifice of memorial, the sacrifice of jealousy; and in the hand of the priest shall be the water of this conviction that brings the curse.

¹⁹And the priest shall adjure her, and shall say to the woman, If no one has lain with thee, and if thou hast not transgressed so as to be polluted, being under the power of thy husband, be free from this water of the conviction that causes the curse.

— Numbers 5:20 —

²¹then the priest shall adjure the woman by the oaths of this curse, and the priest shall say to the woman, The Lord bring thee into a curse and under an oath in the midst of thy people, in that the Lord should cause thy thigh to rot and thy belly to swell;

²²and this water bringing the curse shall enter into thy womb to cause thy belly to swell, and thy thigh to rot. And the woman shall say, So be it, So be it.
